Gary Pendergast f593d8532a Tests: Restore the database connection earlier when switching test groups.
When plugins don't disable the `backupGlobals` PHPUnit option in their own tests, `$wpdb` is backed up and restored between classes of tests. The serialisation process used for this broke the database connection. This previously wasn't a problem, as it was reconnecting before each test.

[38398] introduced some changes that required the connection to be available in `setUpBeforeClass()`, earlier than in was previously reconnecting. This didn't cause warnings in Core, but it did cause warnings for plugins that don't disable the `backupGlobals` option.

The database connection now reconnects in `setUpBeforeClass()`. This change also fixes a few Core tests that weren't calling `parent::setUpBeforeClass()` or `parent::tearDown()` correctly.

Fixes #39327.

The short version:

1. Create a clean MySQL database and user.  DO NOT USE AN EXISTING DATABASE or you will lose data, guaranteed.

2. Copy wp-tests-config-sample.php to wp-tests-config.php, edit it and include your database name/user/password.

3. $ svn up

4. Run the tests from the "trunk" directory:
   To execute a particular test:
      $ phpunit tests/phpunit/tests/test_case.php
   To execute all tests:
      $ phpunit

Notes:

Test cases live in the 'tests' subdirectory.  All files in that directory will be included by default.  Extend the WP_UnitTestCase class to ensure your test is run.

phpunit will initialize and install a (more or less) complete running copy of WordPress each time it is run.  This makes it possible to run functional interface and module tests against a fully working database and codebase, as opposed to pure unit tests with mock objects and stubs.  Pure unit tests may be used also, of course.

Changes to the test database will be rolled back as tests are finished, to ensure a clean start next time the tests are run.

phpunit is intended to run at the command line, not via a web server.
